Question

why is the amount of gas collected in one of the test tube double of the amount collected in the other on electrolysis of water name the gas ​

Answer 1

hey mate... here is your answer

Because water consists of 2 molecules of hydrogen and 1 molecule of Oxygen. Therefore gas collected is double of the other.

The gas is hydrogen.

hope this helps ❤❤

Answer 2

The chemical reaction involved in the electrolysis of water is

2h2o———————>2h2+o2

From the above reaction it is clear that the amount of hydrogen gas and the oxygen gas formed are always in the ratio of 2:1. Therefore the volume of gas collected in the first test tube is double the volume of the gas collected in second
